Strapped into the trunk of a Toyota sedan, the smiling face of a deity draped in plastic flowers rolls slowly down a suburban Long Island street behind a crowd of chanting women in saris. Holding up golden pineapples wrapped in red and gold ribbon, the small parade processes past a car wash and around the block until it returns to the temple, a former synagogue facing the Long Island Rail Road tracks.

The circuit through the neighborhood is meant to make the deity feel at home in its new surroundings. For the Afghan Hindu congregation following along on a recent Sunday, some wearing only socks, the ritual appears to serve a similar purpose.

Before they were forced to wear yellow badges to mark their status as a minority, and before they fled their homeland as persecution and discrimination worsened, the Hindus of Afghanistan were a proud people who traced their history back for centuries.

“We were very happy in Afghanistan living there with our Muslim brothers in harmony and peace — even when the communists came, we were happy,” an elder in the community, Sona Ram, 69, said. “Then they started anti-Hindu propaganda,” he said, referring to the Taliban. “We had to leave.”

Dr. Ram, an orthopedic surgeon who once served in Afghanistan’s Ministry of Health, moved to New York City in 1994 as economic conditions deteriorated in the country and not long before the Taliban began forcing Hindus to wear badges. He brought his family to join others in the tightly knit community that first settled in Flushing, Queens, in the 1980s. He imagined going back someday. Now, as the Taliban-led insurgency in Afghanistan appears to be gaining new ground, the city’s growing community of Afghan Hindus is resigning itself to permanent exile in America.

Generations ago, Hindus ruled Afghanistan, community leaders here say. They started the first banks and were prominent in the business sector, and they were well-respected by their Muslim countrymen. The two groups lived together relatively peacefully, even as their country was riven by ongoing civil conflicts, and skirmishes between Pakistan and India dominated the region’s news.

These days, only a handful of Hindus live in Afghanistan, the leaders say, and the resurgence of the Taliban — highlighted by Vice President Cheney in a trip to Kabul last week — has sent tremors of fear through those who remain. Many of the temples have crumbled, while areas once reserved for Hindu funeral pyres have been taken over by the Afghan government for other uses, the leaders say.

Yet as the Hindu community has faded in Afghanistan, it has flourished here. Community leaders now estimate that about 220 Afghan Hindu families, or 3,000 people, live in and around New York City. In 1998, led by Balram Kakkar, a lawyer who started his own firm, the group founded its first temple on Bowne Street in Flushing, on a strip lined with other Indian temples.

Most Afghan Hindus are Punjabi and have blended into the neighborhood, though the Afghans’ history has kept the ties between them strong. Adjusting to the wider society in New York also has been relatively easy for the community, which held an economically privileged position in Afghanistan. Many have moved out of the city to the suburbs.

In 2005, the temple bought a building in Hicksville, L.I., that was once a synagogue, to replace the smaller space on Bowne Street. In the past few months, the community has been working to get settled at the new location, where leaders now predict they’ll stay for years to come.

Still, many mourn the loss of land and heritage. Some hold on to wistful hopes of return.

On the temple’s Web site, young graphic designers who belong to the temple have posted a futuristic architectural rendering of Kabul. In the picture, the streets are lined with trees and sleek modern buildings. The rendering is based only on their imaginations, however, and Mr. Kakkar said the temple would likely take the picture down soon.

“I would definitely love to go back,” Dr. Ram’s son, Sena Lund, who is also the temple’s secretary, said. “But I’m better off here now.”
